Title: Method of and means for determining unbalance of rotating bodies
IPC: G01M1/22
Filed: 1963-01-30
Abstract: 971,676. Measuring dynamic unbalance. H. H. BEISSBARTH. Jan. 30, 1963 (Feb. 22, 1962), No. 3764/63. Headings G1N and G1X. [Also in Division G4] The magnitude of the dynamic unbalance of a wheel as determined on a balancing machine is modified by a factor depending on the moment of inertia, to obtain the true balancing mass, the moment of inertia being proportional to the mechanical resonant frequency, measured by a tachometer when the unbalance signals are maximum. The true balancing mass is the nominal balancing mass multiplied by the ratio of the resonant frequency of the test wheel to that of a standard wheel. As shown (Fig. 1) the unbalance of the wheel 1 is measured on a recording disc 4, and the rotational frequency by a revolution counter 5 fed with pulses from a generator 6. When the amplitude of oscillation is maximum the pointer of counter 5 is clamped, indicating the resonant frequency of the wheel. Alternatively, as the rotational speed is increased a counting circuit may be switched on when the amplitude of oscillation starts to increase to count the number of pulses from generator 6 in a predetermined time interval which includes the resonant frequency of rotation. Specification 737,543 is referred to.

Abstract: 1523061 Character recognition AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 3 Feb 1976 [14 Feb 1975] 04150/76 Heading G4R Data representing a character to be recongized is stored in a 16 x 16 binary matrix to form a pattern as shown in Fig. 1, where the intersections of the horizontal and vertical lines represent memory address locations M(X, Y) and the areas between the locations are represented by m(X, Y). To determine the nature of the character the matrix is searched for horizontal, vertical, positive diagonal or negative diagonal segments in predetermined areas of the character to determine values # 1 -# 21  (Figs. 3a-3d). Values I D , I V , I G , I H  representing positive diagonal, negative diagonal, vertical or horizontal segments respectively at memory points and are determined by examining pairs of areas along substantially inclined, vertical or horizontal lines to see if both areas lie on the character. For instance Similar equations are disclosed for I G , I V , I H . The values obtained from the equations are used to determine whether the areas shown in Fig. 3a-3d contain vertical, horizontal or inclined lines and if so the approrporate values of # are set equal to 1. It is possible to produce intermediate variables denoting curves in various predetermined sectors (Figs. 24a, 24b, not shown) which are useful for decoding digits 5, 6, 8, 9, 0, and which are obtained from the presence of selected # values. Decoding is performed by examining the # values and the intermediate variables for the presence and absence of predetermined values, e.g. digit 5 requires the presence of a curve a4 with at least a curve a1 and #16 and the absence of a curve a3 and #5, #8, 014, #15.

Assembling force fits.-A device for anchoring the end of a cable or group of strands 3 wherein the strands are pre-stressed and subsequently fastened under the same tension by clamping means which prevent longitudinal sliding or creeping of the strands is characterized in that it comprises T- sectioned curvilinear key members 1 adapted, when assembled, to form longitudinal parallel channels to receive said strands and a cylindrical outer surface over which a cylindrical ferrule 2 is forced to exert a radial inward pressure sufficient to cause the surface of said key members to be compressed by the strands. In an embodiment in which the strands 3 issue from a concrete mass 5 a perforated plate 4 is threaded over the strands and placed against the concrete to act as a bearing member for the keys. 1. The tapered inlet of the ferrule is placed over the keys and the anchoring is effected by a hydraulic ram comprising a cylindrical body 6 carrying at its front end a thrust ring 7 said body housing a pair of opposed annular pistons 8 and 10. The piston 8 is provided with a thrust ring 9 and the piston 10 with a strand gripping device 11 (Fig. 7). In operation the piston 10 is first actuated to tension the strands of the cable and then the piston 8 is actuated to press the ferrule over the keys to complete the anchoring (Fig. 9). For joining the ends of two cables a gripping device 12 is placed in front of the thrust ring 7. The strands 3 and 13 of the cables to be joined are interposed and are arranged alternately in the channels of the key assembly. The plate 4 is replaced by a thrust member 14 (Fig. 11). The piston 10 is actuated to tension that portion of the strands 3 and 13 lying between the gripping devices 11 and 12 and finally the piston 8 is actuated to force the ferrule over the key assembly. The strands form compressions as deep as <SP>1</SP>/ 64  to <SP>1</SP>/ 32  inch in the key surfaces. Prior to the final anchoring operation the strands may be temporarily fastened at a 30 per cent greater tension than that desired for about ten minutes whereafter the tension is reduced to the desired value and the anchoring effected.

Abstract: 364,891. Sewing-machines. FAIRWEATHER, W., 65, Chancery Lane, London.-(Singer Manufacturing Co. ; Elizabeth, New Jersey, U.S.A.) Feb. 11, 1931, No. 4247. [Class 112.] A thread-cutting device arranged below the throat plate of a button sewing-machine comprises a pair of pointed blades one of which 64 detains the last needle loop drawn out of the shuttle 21 and the other subsequently deflects the work limb of the loop to the cutting blade 72. When the machine, which is described in Specification 118,672, [Class 112, Sewing &c.], is started by the lever 32, the blades 63, 64 are turned from the full to the dotted position, Fig. 5, by a linkage 80 where they remain for one or two revolutions of the main shaft 24 according to the number of stitches required. They then fall back to the position shown full and the blade 64 catches the last needle loop formed as the machine comes to rest. On lifting the presser foot by a treadle lever 18 the bobbin thread cutter bar 51 slides forward operated by linkage 55, 56, 57. The bar 51 displaces the blades 63, 64 and the detained needle loop is deflected by the curved edge 71 of the blade 63 to the cutting edge 72. The loop is severed simultaneously with the cutting of the bobbin thread by a knife 52. The blades 63, 64 are restored to the position shown in full by the recovery of a spring 83 when the presser foot is lowered.

A method for straightening elongated hollow bodies comprises passing the body through successive straightening means, without twisting it about its longitudinal axis, to bend the body until the yieldpoint of the material is exceeded, the bending force being applied in steps at intervals along the path of travel so that it is first only bent to below the yield point and then at a position removed from the first application the bending force is increased to exceed the yield point; the initial bending bringing the material close to its yield point and the straightening forces generated being measured, indicated and recorded. The measurement is made by attaching strain gauges to the work, amplifying the signals and feeding them to an indicator and/or a multi-colour or magnetic recorder.
